OK - it was easier than I thought.

Just add

} elseif ($bbuserinfo['usergroupid']=="1") {
	$replybox='';

in the list of conditionals to not show the reply box to guests.

Now the only thing I can't figure out is how to only show the reply box if:
1.) it is the last page of a multipage thread, or
2.) it is a single page thread.

I can use
} elseif ($pagenumber!="1") {
$replybox='';

for example to not show it on page 1 but to show it on page 2.

I see above there is this conditional statement:
if ((!isset($pagenumber) or $pagenumber==0) and $pagenumber!="lastpage") {

Which I thought I would be able to easily adapt, but I can't seem to make it work.

Can anyone give me a hand?
